Clematis is a vigorous, twining vine that produces a profusion of beautiful flowers in a variety of appealing colors of purple, pink, red, blue, and/or white. These magnificent flowering vines can add a splash of color and interest to your summer garden, but they do require some special attention.
Choose a bright area with at least 6 hours of full sun every day to ensure the success of your clematis seed. Plant the clematis root ball 3 to 4 inches deep in well-drained soil with enough organic matter, such as compost.
Cut the vine back to one foot tall after planting to encourage branching. Provide climbing plants with support, such as a trellis, fence, or post. Mulch may help keep the soil cool and retain moisture, according to several gardeners. To stimulate more strong development, feed your plants with a general fertilizer on a regular basis. Water on a regular basis until the plant is established.
Prepare Pots for Planting
Fill a gardening pot to within 1/2 inch of the top with sterile planting mix. Because the clematis seedling has a long taproot, the pot should be deep. Allow the planting mix to soak up the water before draining the container. Clematis seeds will rot instead of germinating if the soil is too damp.
Plant Clematis Seeds in a right depth
Clematis seeds should be equally spaced on the planting mix, with at least 1/2 inch between them. Apply a thin layer of the planting mix to the seeds. 1/4 inch of sand should be placed on top of the seeds and planting mix. Water the pot gently to wet the planting mix while keeping the sand and seeds in place.

Refrigerate the Seeds
The International Clematis Society recommends sealing the container with the sown seeds in a transparent plastic bag. The type of clematis seeds you used should be written on the packaging. Refrigerate the bag for approximately three months. This deceives the seeds into believing there was a cold phase throughout the clematis seed germination process. Stratification is the term for this procedure.
Germinate Clematis Seeds
Remove the seeds from the fridge and place them in a warm, well-lit area away from direct sunlight. While the seeds germinate, keep the soil wet. The clematis variety you are raising determines the germination process. Some clematis seeds take six to eight weeks to germinate, while others take up to three years.
Transplant Clematis Seedlings
Keep an eye out for evidence of clematis seeds emerging. Before transplanting the seedlings into separate pots, let them grow to a height of 2 inches or more. Use the same potting soil that you used for germination. Take care not to injure the seedlings’ lengthy taproots.
When three sets of genuine leaves have grown on the seedlings, pinch the tips to encourage bushing. Until you’re ready to harden off the new plants, keep the little seedlings away from direct sunlight. Ensure that the expanding stems and vines are supported. Expect the seedlings to take three years to mature before blooming.
